The decay of C-10 excited states to the 2p+2 alpha exit channel has been studied using an E/A=10.7 MeV C-10 beam inelastically scattered from a Be-9 target. Levels associated with two-proton decay to the ground state of Be-8 have been observed. These include states at 5.18 and 6.54 MeV which decay by sequential two-proton emission through the long-lived ground state of B-9. In addition, states at 5.3 and 6.57 MeV were found in which there is no long-lived intermediate state between the two proton emissions. For the 6.57 MeV state, the two protons are preferably emitted on the same side of the decaying C-10 fragment.
